The Gaussian antenna, theory and applications

An alternate solution for the fields radiated by a truncated-Gaussian antenna is provided. The aperture distribution is first expanded in a series of Hermite orthogonal functions chosen in a way that allows a direct transformation of the aperture fields to the Fresnel and far fields. The resulting solutions are structured, yielding radiated fields that are constructed sequentially as more terms of the field expansions are used in the computations. Several examples are provided to show the usefulness of the theory.
